MACHINE FOR SHAPINC CYLINDERS.

Application flledMarch 11, 1922. fierial No. 543,047.

a citizen of the United States, and resident of Danbu-ry, in the county of Fairfield and State of Connecticut, have invented'a new and Improved Machine for Shaping Cylinders, of which the following is a full, clear, and exact description.

My invention relates to a machine for shaping cylinders, and aims to provide a device of this character particularly adapted for use in connection with the making of metallic receptacles, although it is not necessarily limited to this particulaar adaptation.

vide a machine of the type specified by means of which a cylinder may be treated to form a flange orcorrugation in the body of the same, controlling meansbeing also provided which will permit of an operator accomplishingthis operation with that degree of nicety insuring the production of a perfect article.

A further object of this invention is that of providing a device of the'character stated in which means will be provided serving at all times to retain the :cylinder in proper position with the operating parts of the machine, so that the portion desired will be perfectly formed therein.

Further objects of this invention will become apparent in the annexed specification taken in connection with'the drawings which latter illustrate one practical embodiment ofthe same, and in which;

Figure 1 is a sectional end view of a cylinder-shaping machine embodying my improved construction and showing thesame in operation.

Fig. 2 is a view similar to Fig. 1 but showing the position assumed by the parts upon the operation being completed,

Fig. 3 is a sectional side View of the said machine, and I Fig. 4 is an enlarged fragmentary eleva tion of one of the forming rollers and associated mechanism.

It will be seen in these views that the reference numeral 5indicates the base of the machine which serves to rotatably support a drivin shaft 6 the lattercarrying in a manner hereinafter described, thecylinder 7 which is to be operated upon.

- As has also been shown, a second shaft 8 It is an object-fifthis invention to pro-.

a seriesof radially isrotatably carried by -a yoke 9, and the latter is pivoted to a standard 10 carried by the base 5, and with a view of deliberatel rocking the yoke it will be noted that I pref erably employ a shaft 11 havin one of its ends connected by screw thread s' 12 to the yoke 9, its opposite end carrying a hand wheel 13 b means of which the shaft 11 may be. b0 y rotated, it being noted that this rotation will serve to swing the lower end of the yoke 9, causing a corresponding movement on the part of the upper end thereof. 7

I Furtherit will be notedthat a shield 14 is provided, which shield is carried adja cent the outer end of the base 5, it bein noted that the shaft 6 extends through and beyond the same. Also rollers 15 are carried by the shield, and-two pairs of supporting r01 ers 16 and 17 extend outwardly from this member, it being noted that these latter rollers are arranged in different planes for a purpose hereinafter specified;

Now with a view of providing a forming medium it will be seen that the shaftsv 6 an 8 carry female and male-forming rollers 18 an 19 respectively which are preferably split and positioned at points adjacent the shield 14, and it will also be seen that a pair-of collars 21' and 21 are'carried by the shaft 8 at a point beyond the roller 19. These collars rotatably support crank arms 22 and 23, the lower end of each of which carries a pair of contact rollers 24. To provide means serving to normally press these latterfrollers downwardly, I preferably utilize a bolt 25 having one of its ends swingin'gly secured as at 26 to the upper end of the upper crank arm 23, its body in slidable engagement with the upper end of. the crank arm 22 while a spring 27 is disposed between these two arms and around the body of the boltto press the,

said arms in opposite directions. Also to maintain the contact rollers 24 at all times equi-distant from the center of the shaft 6 disposed anti-friction g as well as the shaft 8 7O its body 7 disposed over the extended end of the shaft 6 and the forming roller 18 carried thereby, it being of course appreciated that the shaft 11 is previously operated to swing the upper end of the yoke 9 upwardly to a point at which-the forming roller 19 will not interfere with the application of the cylinder 7 to the operating porti0ns of the machine as in Fig. 2. Also it will be noted that, incident tion that the inner edge of the same isheld out of contact with the shield 14 by the rollers 15.

The hand wheel 13 may now be operated to cause the inner end of the yoke 9 to be pushed outwardly, and this movement will cause its outer end to be moved inwardly towards the shaft 6. Incident to the fact that the said yoke carries the shaft 8 it will be appreciated that this movement will also cause the male forming rollers 19 and the contact rollers 24-, to be moved towards the outer face of the cylinder or drum 7, it being noted, however that the crank arms 22 and 23 and the rollers 2 L carried thereby are held in proper position incident to the proper guiding action afforded by the inclined slot 29 and the pin 30. Thus the rollers 24: will serve as stabilizing agents and incident to thefact that these rollers extend to both sides of the arms 22 and 23 it will be obvious that this stabilizing action will be enhanced to a maximum extent. A continuation of the movement of the yoke 9 will result in the contact rollers being pressed into engagement with the outer face of the drum, thus forcing the inner face of the same into intimate contact with the forming rollers 18 and the male forming rollers 19 will now engage the outer face of the drum to form the desired flanges adjacent the edge of the same.

Also in this connection it will be noted that if it is desired to corrugate the body of the drum 7, this may be accomplished by simply securing suitable male and female rollers 33 and 34 to those portionsof the shafts 8 and 6 respectively extending beyond the forming rollers 18 and 19. Thus when this expedient is resorted to it will be appreciated that simultaneously with the cooperation of the rollers 18 and 19 a co-op eration of the rollers 33 and 34 will be ef .fected to provide the corrugations aforementioned. Further incident to the fact that the forming rollers 18 and 19 are preferably split it will be obviously understood that any desired form of corrugation may be provided by simpl detaching the major portions of these ro lers from the bodies of the shafts and substituting that type of roller which is to effect the result desired.

Obviously the speed of rotation of the shafts 6 and 8 may be any desired rate, and an operator may also move the yoke 9 with that degree of speed which will insure the mostzefiicient contact being established between the forming rollers and the face of the drum to be flanged and corrugated. Further it will be noted that by means of the spring pressed collar 32, that the cylinder or drum 7 will at all times be prevented from becoming distorted, aside from the fact that this member will initially serve to hold the inner edges of the drum in contact with the rollers 15 until such time as the flange begins to form in the body of the drum.

Further, incident to the fact that the rollers 17 are preferably shaped to correspond to the shape of the rollers 18 it will be noted that as the inner edge of the drum 7 moves out of contact with the rollers 15, incident to the flange being formed in the same, that the said rollers 17 will act as guides and will ride in the track provided bythe flange portionnof the drum 7 thus precluding any possibility of movement on the part of the body of the cylinder 7 other than purely rotational. I

' Finally it will be seen that after the contact rollers 24 have been moved initially into contact with the outer face of the cylinder to be operated upon by the action of the elements 25, 26 and 27 these elements will continue to press against the outer face of the drum until the forming roller 19 is moved to its nearest position with respect to the forming roller 18, the pants in this position being shown in Figs. 1 and 3. a
